How to Clean a Composite Deck: Simple Steps to Keep It Looking New for Years!

Composite decking is taking over backyards everywhere — and it’s no wonder why. With stunning patterns, superior performance, and minimal maintenance needs, composite decks deliver unmatched convenience and style. However, while they require far less upkeep than traditional wood decks, occasional cleaning is still crucial to preserve their beauty and ensure long-term durability.

 

If you're wondering how to clean your composite deck the right way, you're in the perfect place! Whether you’re a seasoned homeowner or a new DIY enthusiast, this guide will help you keep your composite deck spotless and vibrant — effortlessly.

Why Composite Decks Are the Smart Choice

Before diving into the cleaning steps, let’s appreciate why so many homeowners are switching to composite decks:

  • Exceptional Durability: Unlike traditional wood, composite materials resist rot, cracking, and insect damage.

  • Low Maintenance Costs: No staining, sealing, or heavy repairs needed — saving you both time and money.

  • Diverse Styles and Patterns: Composite decks offer a stunning range of textures and colors to match any home design.

  • Easy Installation and Cleaning: With systems like Praysun’s 360-degree co-extruded decks, installation is straightforward, and surfaces stay cleaner for longer.

 

Modern co-extrusion technology makes composite decks even more robust. For example, Praysun’s edge-sealed composite decks boast low water absorption and strong water resistance, helping them resist stubborn stains. Plus, Praysun offers beautiful, customizable options — making it easier than ever to create your dream outdoor space.

The Importance of Regular Cleaning

Even though composite decks are low-maintenance, dirt, leaves, and spills can still accumulate over time. Regular cleaning:

  • Enhances the deck's appearance

  • Extends its lifespan

  • Prevents the buildup of mildew and mold

  • Preserves color vibrancy

According to studies, homeowners who clean their decks two to three times a year see a 30% increase in deck lifespan compared to those who don't!

How to Clean Your Composite Deck in 5 Easy Steps

Ready to refresh your deck? Here's a simple, actionable plan:

1. Gather Your Cleaning Supplies

You'll need:

  • Warm water

  • Mild soapy water (dish soap works perfectly)

  • A soft nylon brush

  • A garden hose

  • A bucket

 

Important: Always check the deck manufacturer’s cleaning guidelines. Avoid cleaners with sodium hypochlorite (bleach), which can corrode and fade your deck's surface.

2. Prepare the Deck Area

Before getting started:

  • Remove all furniture, decorations, and plants.

  • Sweep away loose debris like leaves, dust, and dirt.

  • Inspect for any large stains or problematic spots.

 

Clearing the surface not only makes cleaning easier but prevents scratching while scrubbing.

3. Rinse the Deck with Warm Water

Use your garden hose to rinse the entire surface with warm water. This removes initial dirt, dust, and debris, making scrubbing more effective.

 

4. Scrub with Soapy Water

Dip the nylon brush into the bucket of soapy water and scrub gently. Focus on:

  • High-traffic areas

  • Any stains or buildup

  • Board gaps where dirt may accumulate

 

Work in small sections, and scrub in the direction of the wood grain (even for composite boards) for the best results.

5. Final Rinse and Dry

Once you’ve scrubbed the entire deck:

  • Rinse thoroughly with clean water to remove soap residue.

  • Let the deck air dry completely before moving furniture back.

In just a few hours, your composite deck will look refreshed, vibrant, and ready for action!
